Code Description

ICD-10 F32.4 is a billable code used to indicate a diagnosis of major depressive disorder, single episode, in partial remission.

Key Diagnostic Point:

F32.4 refers to a major depressive disorder characterized by a single episode where the patient has shown some improvement in symptoms but is not fully recovered. This condition is marked by persistent feelings of sadness, hopelessness, and a lack of interest or pleasure in daily activities. In partial remission, the individual may still experience some depressive symptoms, but these are less severe than during the acute phase of the disorder. The diagnosis requires careful assessment of the patient's mood, functional impairment, and any history of previous depressive episodes. Treatment often involves a combination of psychotherapy and pharmacotherapy, including mood stabilizers and antidepressants. Regular monitoring for suicide risk is crucial, as individuals with major depressive disorder have an elevated risk of self-harm and suicidal ideation, particularly during periods of exacerbation or when transitioning between treatment phases.
